WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 443,341, dated December23, 1890.

Application filed September 18, 1890. Serial No. 364,970. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY C. TVEEDEN, of Quincy, in the county ofNorfolk and State of Massachusetts, a citizen of the United States, haveinvented certain new and useful Improvements in Vvater Closet Bowls, ofwhich the following is a specification.

My invention relates to water-closet bowls of the kind which are emptiedby siphonic action. In such bowls the bottom of the basin is so formedas to retain a body of water, which fills the same after the flushingoperation has ceased. These bowls are ordinarily formed of one piece ofearthenware. In these bowls as heretofore constructed it is often thecase that an insufficient supply of water remains in the bowl after theflush has ceased. The object of my present improvement is to correctthis and to insure a sufficient supply.

In the accompanying drawings I have represented a water-closet bowlembodying my present improvement in the form now best known to me.

Figure 1 is a vertical section, and Fig. 2 a plan. Figs. 3 and 4. arehorizontal sections at 00 0c and y y of Fig.1. Fig. 5 is a verticalsection at z z of Fig. 4.

I will now'describe the apparatus shown in the drawings. This consistsof a bowl A, having a siphon-formed discharge-pipe B, one end of whichcommunicates with the bottom of the bowl, while the other is connectedto the soil-pipe or other point of discharge of the contents of thebowl. The bowlA is provided with a flushing-horn O, to which theflushingpipe is attached, and also with a flushing-rim I), through whichflushing-water is distributed around the sides of the bowl.

In the rear of the bowl, and between it and the flushing-horn,I form apair of watenpockets E E, (see Figs. 3, 4, and 5,) arranged, forconvenience, on either side of the dischargepipe B. These water-pocketsD D, Iprovide at their lower part with small perforations or weep-holese, passing through the wall of the bowl and communicating with itsconcave bottom; also in the wall of the bowl, at a point communicatingwith the flushing-rim and substantially opposite the fiushinghorn, Iprovide a water-passage F, (see Figs. 1 and 3,) through which, after theflushing-water has entered and filled the pockets above mentioned, itscontinued flow may pass through the flushing-rim to flush the bowl. Thesi phon discharge-pipe is represented as provided with a jet-hole G (seeFigs. 1 and 3) to start it, this being a well-known device for thepurpose, and forming no part of my present invention.

The operation of the device is as follows: WVhen water is turned on toflush the closet, it passes down through the flushing-pipe and entersand fills the pockets E E, which, it should be observed, are of acapacitysutficient to contain enough watcrto fill the bowl to thedesired height, after the flushing operation has ceased, by percolationthrough the contracted orifices e e, above described, at the lowerportion of the pockets. The pockets having thus been filled, the surplusflushingwater passes to the bowl, which is flushed in the ordinarymanner by siphonic action. When this ceases, the water, as is wellknown, will stand at a low level in the bowl. The subsequent gradualdischarge of the water contained in the pockets E E into the bowloperates to fill the same with water to the desired higher level.

I do not claim, broadly, the combination, with a bowl of the characterdescribed, of a chamber within which a part of the flushingwater may becaught and afterward suffered to flow out into the bowl throughrestricted discharge-0rifices to fill the same to the desired height. Myimprovement consists in so constructing and locating the pocketsrelatively to the bowl and flushing-horn that flushing-water firstenters the pockets and fills them, thereby insuring a sufficiency ofwater therein regardless of the subsequent length of the flushingoperation of the bowl proper. devices, in which the great bulk of theflushing-water passes immediately to the bowl to flush it, only aportion being diverted into the storage-pockets and filling them whilethe flush continues. With such a construction, unless the flush iscontinued for a sufficient length of time, these pockets will not befilled full, and hence sufficient water will not be retained by anddischarged from them to fill up the bowl to the desired height.

I claim- The improved water-closet bowl herein de- This is animprovement upon prior IOO scribed, having a siphon outlet-pipe 13, apair the said Water-retaining chambers being p roof Water-retainingchambers E E, located upon vided with restricted orifices a a, allsubstaneither side of the bend of the siphon-outlet tially as set forth.and communicating at their upper portions, In testimony whereof I havehereunto sub- 5 as shown, a flushing-horn C, communicating scribed myname this 12th day of September, 15
